Drone mitigation methods and apparatus

Abstract

Systems and methods for drone mitigation, or the deterrence of aerial drones from flying in an given area, are described. The systems and methods take advantage of the fact that destabilization of a drone can be accomplished by externally changing the performance of one or more of its propeller driven systems. In doing so, the drone is incapable of maintaining stability in flight, thereby causing the remote controlled pilot to force a retreat, or risk and result in a crash of the drone. Embodiments utilizing sonic energy and liquids are described.

The invention claimed is: 
     
       1. A sound-based drone mitigation system comprising:
 an array of sonic transducers operative to produce sonic energy sufficient to cause resonances on the blades of a rotor and; 
 wherein the resonances are produced by broadband and or narrowband sonic energy transmissions and wherein the resonances are at sonic frequencies. 
 
     
     
       2. A sound based drone mitigation system comprising:
 an array of sonic transducers operative to produce sonic energy sufficient to cause resonances on the blades of a rotor and; 
 wherein the resonances are produced by broadband and or narrowband sonic energy transmissions and wherein the resonances are at ultrasonic frequencies. 
 
     
     
       3. A sound-based drone mitigation system comprising:
 an array of sonic transducers operative to produce sonic energy sufficient to cause resonances on the blades of a rotor; and 
 wherein the resonances are produced by broadband and or narrowband sonic energy transmissions and wherein the resonances are at infrasonic frequencies. 
 
     
     
       4. The system of  claim 1  wherein there the sonic energy transmissions comprise ultrasonic energy. 
     
     
       5. The system of  claim 1 , wherein the sonic energy transmissions comprise infrasonic energy.
